FCMEN: Fail-Safe Clock Monitor Enable bit
1 = Fail-Safe Clock Monitor is enabled
0 = Fail-Safe Clock Monitor is disabled
IESO: Internal External Switchover bit
1 = Internal/External Switchover mode is enabled
0 = Internal/External Switchover mode is disabled
CLKOUTEN: Clock Out Enable bit
1 = CLKOUT function is disabled. I/O or oscillator function on RA6/CLKOUT
0 = CLKOUT function is enabled on RA6/CLKOUT
BOREN<1:0>: Brown-out Reset Enable bits⁽¹⁾
11 = BOR enabled
10 = BOR enabled during operation and disabled in Sleep
01 = BOR controlled by SBOREN bit of the BORCON register
00 = BOR disabled
CPD: Data Code Protection bit⁽²⁾
1 = Data memory code protection is disabled
0 = Data memory code protection is enabled
CP: Code Protection bit⁽³⁾
1 = Program memory code protection is disabled
0 = Program memory code protection is enabled
MCLRE: RE3/MCLR/VPP Pin Function Select bit
If LVP bit = 1:
This bit is ignored.
If LVP bit = 0:
1 = RE3/MCLR/VPP pin function is MCLR; Weak pull-up enabled.
0 = RE3/MCLR/VPP pin function is digital input; MCLR internally disabled; Weak pull-up under control of WPUE3
bit..
PWRTE: Power-up Timer Enable bit⁽¹⁾
1 = PWRT disabled
0 = PWRT enabled
WDTE<1:0>: Watchdog Timer Enable bit
11 = WDT enabled
10 = WDT enabled while running and disabled in Sleep
01 = WDT controlled by the SWDTEN bit in the WDTCON register
00 = WDT disabled
Note 1:
2:
3:
Enabling Brown-out Reset does not automatically enable Power-up Timer.
The entire data EEPROM will be erased when the code protection is turned off during an erase.
The entire program memory will be erased when the code protection is turned off.
